These types of sounds would be the equivalent of voices music radio or television audio in the context of a multi-family building. The term STC translates to Sound Transmission Class and is measured and stated in accordance ASTM Standard number C634 and tested via the test methodology of ASTM Test Methods E 90 E 336 and E 596.

IIC Rating Definition:

The term IIC refers to the statistical measurement standards used to quantify the transmission of impact sound energy through a floor/ceiling assembly system. These types of sounds would be the equivalent of foot traffic dropped articles or furniture moving in the context of a multi-family building. The term IIC translates to Impact Isolation Class and is measured and stated in accordance to ASTM Standard number C634 and tested via the test methodology of ASTM Test Methods E90 C423 E 548 E 717 and E 989. In addition a new test protocol for concrete sub-floors has been introduced under ASTM E 2179-01. When done in an accredited test laboratory these values are stated as a number to the right of the initials IIC. When done in the "Field" using ASTM Method E-1007 these values are designated by the initials FIIC to the left of the numeric value.IIC values are not heavily influenced by the presence of solid mass in the structure. IIC values are dependent on the presence of a resilient material somewhere in the assembly to isolate and absorb the sonic energy created by impacts.
